Abstract

Abstract Gas-liquid chromatography (GLC) was compared to the official AOAC method for the quantitative determination of fusel oil in distilled spirits on 12 samples by 12 collaborators. Results indicated that the GLC procedure described is at least as accurate as the official procedure. Analyses of 26 distilled spirits samples showed that the GLC method was sensitive and capable of reproducing fusel oil content in the 0—10 g/100 L range to ± 0.03 g/100 L. It is recommended that collaborative studies be conducted on the GLC determination of fusel oil, and that work be extended to include analysis of other important congeners in distilled spirits such as ethyl acetate, acetaldehyde, and methanol.
